Bachmann appeared on the CBS program "Face the Nation" Sunday. She said she is reserving the right to endorse someone, but at this point she hasn't made a decision.

She said she wants to be a unifying person in the Republican Party and she wants to help bring disaffected Democrats and independents to the GOP. She says, "We need to be victorious, and that is where my heart is."

Bachmann dropped out of the presidential race earlier this month. And last week, she said she would seek a fourth term in Congress.
